actually tony if you buy any sort of any decent powerwasher you should at least go with one at 4gpm and 4000psi i prefer going with a 5.5gpm machine that is 3500psi(im a powerwasher as a job so i have access to many different ones...) and top that off with a hot box... and crank the heat up to 190degrees and then your having some fun.. i havent used the wet sand blaster but i would think it would work great
